To @it wltont t maar concern:

Be it'known that LMonsn' S'rnwknr, a citizen ofthe United States,residing at DeM troit, .county oi' Wayne, State ol' Michigan, haveinvented a certain new and useful 'mprovement in Gasiiers; and l declarethe following to be a full, clear, and exact .description of the same,such as will enable 'others skilled in the artto which it pertains tomake and use the same, reference being had to the accompanying'drawings, which form a part of this specification` My -invention relatesto an improvement in gasiiiers, an apparatus for producing a tiled orsuperheated gas from .liquid hydro-earbons, shown in the accompanyingydrawings, and more particularly set forth in the following specificationand claims.

In the drawings; Figure Y1 is a cross-sec tional view through myinvention showing parts in elevation. Fig. 2 is a horizontal seetionalview through the same showing parts in plan. Fig. 3 is an elevation ot agas engine showing the connections between the same and the gasiier,-theordinary carbureter, the gasolene pump and the connec tion betweenit-and the source of gasolene sup ly.

T e object of my invention is to put upon the market an apparatus thatwill convert into what may be regarded as a lxed or dry gas. Iaccomplish this result lby conducting the gasolene through coils in achamber containing the het gases from the exhaust of the engine Thegasolene alter traversing the coil and being subjected. to the heat ofthe exhaust is aiiteri 7'ard released in an inner chamber ,-atthis-pointthe ex haust gases from the engine' are also introduced,which, commingling with the spheroidal particles of the releasedgasolene, conipletely gasiiies the gasolen e sphoroids and at the sametime superheats the gas.

.Referring to the letters of reference shown on the drawiigs, A is'thegasi 1er; B is a gas engine; C is a gasolene pump operated by saidengine; C is a pipe to conduct the gasosource of supply tothe pum g C2,is a pipe leading from the pump to tllie gasiier.

D is a carburetor of any suitable type, D is a pipe to conduct the gasfrom the inner chamber of the gasiiier to the carburetor and D2 a pipeleading from the carbureter to the com ustion-olmml,er oi the engine.

lll is a pipe to conduct the exhaust :from

. coil C3 connected with 'wardly projecting end .sleeve maybenxedlysecured to the stem I the engine to the gasilier and E is an exhaust pipe leading' from the gasiiier to the muffler or atmosphere.

Referring now more particularly to the construction of the ,gasinen itwill be seen by reference to Figs. 1 and 2, that it consists of an outerjacket. A inclosing the inner chamber F suitably supported within thesame. .Surrounding the inner chamber is a the pipe C2 leading from thegasolene pump, the end of the coil C3 terminating in a valve casing Gsupported in thewalls of the inner chamber F. The casing G forms a seatfor two valves, viz.,

the needle valve g, controlling the admission Patented May 14, 1907.

of gasolene to the interior of the inner cham ber, and the valve G,closing the ports G2 through which pass exhaust gases from the engine tothe inner chamber. The needle valve g is provided with a dollector gdesigned to encounter the incoming gasolone to project it downwardly andover the incomin exhaust gases admitted through the ports l g2 is thestem of the needle valve g slutably guided in a bracket arnx G3 attachedto the wall of the inner chamber. y

g3 is a spider-frame formed in the upper portion ot the valve G/ andresting on the dellector g/ ofthe needle valve g, the constructionproviding means whereby on' opening or closing the needle valve g thevalve G will be likewise operated.

H and H/ are diaphragms secured in the upper and lower faces of theinner chamber respectively.

I and. I are stems projecting into the inner j chamber from the centerof thediaphragnis, the stems I being preferablyscrew threaded to engagea sleeve I2 also inelosing the up of the stein l. The

K is a collar secured to projecting lugin which is The operation of thisreadily understood. from the source C `in the `gasilier under slutal thevalve f7 controllin inner chamber. lkfl the stem having a pivoted thevlever J.

Gasolene is'. pumped Hin is a projecting lug on the sleeve l2 to ol.supply .through the coils^ lOO IOS

invention will be p llo the coils, it is subjected to the action of theLheat of' the exhaust delivered from the engine through the pipe E. rifhetemperature of the gasolene is thus materially raised and the pressureci the exhaust gases bearing on the diaphragms II and H serves todepress them, thereby operating the inwardly projecting stems I, I, andthe sleeve connected with the rocking lover J. The construction andarrangement of these parts provide for an extended movement of theAlever J, which raises the valvesg and G, admitting the exlia;.st gasesand gasolene to the innerchainber, the latter entering ina sphern oidalcondition is de'ected downwardly in the forni of any encircling apronsurrounding the incoming exhaust gases. This action results in aconnninfdinv ol the two b fwhich 2D 2D I a complete vaporization isobtained, producing what may be regarded as a fixed or superheated Thebalance'ol: the exhaust 'from the engine, as will be readily understood,passesiout throughthe pipe E to the muffler or atmosphere.' Thesuperheated gas from the inner chamber passes out through the pipe D tothe carliureter or mixer D, Where an explosive mixture' is formed whichpasses to the engine. lOn the vcutting off oi' the exhaust from theengine,

the pressure the outer chamber drops below that of the inner chamber.vThis results in distending the diaphragins due te the pressure of thegas in the inner chamber, thereby forcing the valves to their seats.
